I've been reworking a couple of applications and wanted to clean up the form validation when I came across the Prototype Javascript Framework (http://prototype.conio.net/) and Script.aculo.us. I wouldn't have gotten anywhere without the excellent demo and example from Andrew Tetlaw here:
http://tetlaw.id.au/view/blog/really-easy-field-validation-with-prototype/
It's really easy to implement - we're talking five lines of js, add class references to your form items - like class="required validate-number" and you're done!.
